class_docstr: Produce suggested sets of problem's parameter space to try out.
  
  It uses an `Experiment`s `BaseAlgorithm` object to observe trial results
  and suggest new trials of the parameter `Space` to be evaluated. The producer
  is the bridge between the storage and the algorithm.
docstr: Observe a trial to update algorithm's status
